Installation Requirements

Mounting the Remote Human Interface (RHI) Panel

The installer must provide all mounting hardware such as; hand tools, electrical boxes, conduit, screws, etc. Refer to Figure I-PR-32 on page 60 for the mounting hole and knockout locations.

Procedure

Follow the procedure below for mounting the remote HI panel on a 4” by 4” electrical junction box. Place the microprocessor in a clean dry location during the enclosure mounting procedures to prevent damage.

1.Mount an electrical junction box in the wall so that the front edge of the box will be flush with the finished wall surface.

2.Prior to mounting the panel, the microprocessor module must be carefully removed from the enclosure. To remove the module:

a. Lay the remote panel face up on a flat surface and remove the locking screw from the right hand bottom end of the panel.

b. Remove the recessed hinge screw from the left hand bottom end of the panel.

c. Unlatch the door of the enclosure as if to open it, and slide the left hand side of the door upward away from the hinge. Lay it aside.

d. With the key pad visible, remove the two (2) screws located on the right hand side of the key pad.

e. Carefully slide the key pad plate upward from the bottom, releasing the extruded hinge pin from its socket at the top.

f. Set the microprocessor aside until mounting is complete.

3.Remove the junction box knockout in the back of the enclosure.

Note: The top of the enclosure is marked “TOP.”

4.With the enclosure in the correct position; align the mounting holes around the knockout in the enclosure with the screw holes in the electrical handy box and secure with the appropriate screws.

5.Replace the microprocessor within the enclosure as follows:

a. Verify that the terminal block jumpers are connected properly.

b. Slide the extruded hinge pin at the top left of the key pad plate into the hole located at the top left hand side of the enclosure.

c. Slide the bottom of the plate into place, aligning the two (2) clearance holes with the screw holes on the right. Install the screws but do not tighten at this time.

Note: If the two screws are not installed as called out in the previous step, hold against the key pad plate while installing the door in the next step, to prevent it from falling out.

d. Slide the extruded hinge pin at the top left of the door into the hole located under the bottom left side of the display.

e. Install and tighten the hinge screw located at the bottom left side of the enclosure.

Wall Mounting the RHI Panel

1.Prior to mounting the panel, the microprocessor module must be removed from the enclosure. Complete step 2 in the previous discussion, “Mounting on a 4 in. x 4 in. Electrical Box,” before proceeding.

2.With the microprocessor removed, refer to Figure I-PR-31 for the location of the mounting holes to be used for wall mounting.

3.Place the enclosure against the mounting surface and mark the mounting holes.

Note: The top of the enclosure is marked with “TOP.”

4.With the enclosure in the correct position, remove the enclosure and drill the necessary holes in the surface for the appropriate fasteners, (plastic anchors, molly bolts, screws, etc.)

5.Remove the necessary knockouts for the wire or conduit entry before mounting the panel.

6.Place the enclosure back onto the surface and secure it with the appropriate screws.

7.Follow step 5 in the previous section, “Mounting on a 4” by 4” Electrical Box,” to replace the microprocessor within the enclosure.
